Most computer architecture books are just too technical and complex. Focusing on specific technology, they often by-pass the basics and are outdated as quickly as technology advances. Now you can give your students a gentle introduction to computer architecture and systems software that will provide the appropriate amount of technical detail they need to make successful decisions in their future careers. This text covers the basics in an accessible, easy to understand way. Organized in a form that parallels an actual computer system, entire sections are devoted to principles of data, hardware, and software, to emphasize the importance of computer structure. Assuming only basic knowledge, these sections build up to an in-depth understanding of each topic and how they interrelate to make up a computer system.
